Kind Words from a Teaching Assistant

Memorable Dinosaur Workshops in Schools

Most of us can remember things that we did at school, field trips, summer excursions, special assemblies and so on.  With Everything Dinosaur having delivered something like three hundred dinosaur and fossil themed events and workshops over the last few  years, we like to think that in our own small way our work in schools has contributed to those happy memories.

Whilst on a return visit to a school to work with a Early Years Foundation Stage (EYFS) class, we were pleased to hear from a teaching assistant how fondly her own children remembered a visit from Everything Dinosaur to their classroom.  It seems our tactile fossil handling activities made quite an impression.  The Teaching Assistant dropped us a line to let us know what an effect our workshops had.

Thank you Everything Dinosaur

Children still remember an Everything Dinosaur workshop.

We encourage children to write letters to us, after all, this is a good way for Key Stage One and Key Stage Two pupils to practice handwriting, sentence construction and the layout of letters, but we also appreciate feedback from the grown-ups too.

The Teaching Assistant wrote:

“My own children participated in this session when in Reception, they were very jealous this morning.  Alexander is now in Year 8 and Charlotte is in Year 5 now.  It is a fantastic memory which was so inspiring for them.  Thank you!”

Thank you for your kind words, it is always nice to get feedback and to receive comments from those who have had the opportunity to see one of our workshops.

Digitalised Dinosaur Leads to Dorking Museum Discovery

When is an Iguanodon Not an Iguanodon?

Yesterday, Everything Dinosaur reported on the discovery of a giant whale tooth found in Beaumaris Bay (Victoria).  This significant fossil find, once again highlighted the importance of amateur fossil hunters when it comes to contributing to the Earth Sciences.  You don’t have to travel all the way to Australia to play your part, sometimes the geological collection housed at your local regional museum can provide an opportunity for you to make you mark.

Take for example, the vertebrate fossil collection at Dorking Museum and Heritage Centre.  Student Tom Fedrick has helped re-classify dinosaur tail bones originally described as belonging to an Iguanodon, but keen-eyed Tom, using knowledge gained from four years volunteering at the Museum, concluded that a centrepiece of the collection represented the bones of an entirely different, albeit related dinosaur – Mantellisaurus.

Digitalising the Dorking Museum Collection

Much of the fossil collection is currently being catalogued digitally.  This will enable the collection to be accessed by other museums, researchers and academics.  A-level student Tom has been working on this substantial project and having completed work on around half of the collection, he turned his attention to the Iguanodon exhibit.

Tom explained:

“Looking at it [the Iguanodon exhibit] in the past I always thought it was odd, thinner than I would expect.  However with the catalogue entry in front of me my suspicions were confirmed: this was not an Iguanodon.  Though it was listed as Iguanodon atherfieldensis my background knowledge meant I knew that this species had been reclassified as a new genus entirely – Mantellisaurus by Gregory Paul in 2007.”

The Problem with Iguanodontids

The fragmentary nature of iguanodontid fossils excavated from various locations across the south of England have presented palaeontologists with a number of taxonomic puzzles to solve.  Iguanodon was the second dinosaur species to be named and described (although the genus name was erected before the Order Dinosauria had been established).  Gideon Mantell named Iguanodon, but at the time his paper was published, he failed to establish a holotype or indeed assign a trivial name to his specimen.  From that point on, the Iguanodon genus became a sort of dumping ground for any large Ornithischian dinosaur fossil material excavated from the Weald Clay Formations and the contemporaneous Wessex Formation of the Isle of Wight.

A spokesperson from Everything Dinosaur commented:

“It’s complicated!  Lots of fossils found in Europe, Africa and North America formerly ascribed to Iguanodon, have been re-classified since the turn of the Century.  The holotype material for Iguanodon bernissartensis for instance, a genus synonymous with the term “English dinosaur”, has been reassigned to more complete Belgian fossil material and we congratulate Tom for spotting the incorrectly labelled museum specimen.”

Mantellisaurus

Mantellisaurus atherfieldenis  was established in 2007 by the American Gregory Scott Paul.  It is a more gracile animal than the robust Iguanodon bernissartensis  and considerably smaller, perhaps around seven metres in length.  Analysis of the forelimbs suggest that Mantellisaurus spent the majority of its time as a biped, although it could adopt a four-legged stance when desired (facultative quadruped).

The picture above compares the skeletons of three types of iguanodontids.  Although, Gregory S. Paul regarded Dollodon bampingi as a valid genus, more recent research suggests that Dollodon might be a synonym of Mantellisaurus.  The term “Nomen dubium” is given to any organism whose validity is in doubt.

This is the second time that a fossil specimen has been reclassified after research undertaken at the Dorking Museum and Heritage Centre.  Last year, Everything Dinosaur reported upon the reclassification of a marine reptile specimen, thought to have represented Polyptychodon interruptus.

The programme of digitally logging the collection at the Dorking Museum and Heritage Centre is progressing.  It is thanks to dedicated, hard-working individuals that our country continues to be blessed with a wealth of regional museums which contribute so much to our understanding of the world

Dorking Museum opening times: Thursday, Friday and Saturday, 10am – 4pm.
Admission: Adults £2, Concessions £1, Under-5s free, Family ticket £4.50 (prices correct at time of publication)
